Scene: The Back Patio. John and Arthur are taking a break from using trowels to dig out dirt for a step.
Arthur: Uhhn! (Points and reaches for garden shears that John has moved about three times already).
John: No, Arthur. Those aren't for you. (Thinks about ways to explain why that don't involve pantomiming a severed finger.) See? (picks up safety locked shears; squeezes handle so the blade wiggles impotently against the anvil; runs index finger over the side of the blade.) Ouch. See, this part can cut you. Ouch.
Arthur: (Eyes go wide and he giggles) Ouch! (Reaches for shears.)
John: (Mentally slapping forehead) Ugh. You're not supposed to like it.

Mark: What have you been teaching the child? He keeps pointing at things and saying 'ouch ouch.'
